Switched Feedback for the Multiple-Access Channel
Oliver Kosut, Michael Langberg, Michelle Effros
A mechanism called switched feedback is introduced; under switched feedback, each channel output goes forward to the receiver(s) or back to the transmitter(s) but never both. By st…
Characterizing positive-rate key-cast (and multicast network coding) with eavesdropping nodes
Michael Langberg, Michelle Effros
In multi-source multi-terminal key-dissemination, here called ``key-cast,'' introduced by the authors in [ITW2022], network nodes hold independent random bits, and one seeks a comm…
Nobody Expects a Differential Equation: Minimum Energy-Per-Bit for the Gaussian Relay Channel with Rank-1 Linear Relaying
Oliver Kosut, Michelle Effros, Michael Langberg
Motivated by the design of low-complexity low-power coding solutions for the Gaussian relay channel, this work presents an upper bound on the minimum energy-per-bit achievable on t…
Perfect vs. Independent Feedback in the Multiple-Access Channel
Oliver Kosut, Michelle Effros, Michael Langberg
The multiple access channel (MAC) capacity with feedback is considered under feedback models designed to tease out which factors contribute to the MAC feedback capacity benefit. Co…
Multiple Key-cast over Networks
Michael Langberg, Michelle Effros
The multicast key-dissemination problem over noiseless networks, introduced by Langberg and Effros [ITW 2022], here called the ``key-cast'' problem, captures the task of disseminat…
Third-order Analysis of Channel Coding in the Small-to-Moderate Deviations Regime
Recep Can Yavas, Victoria Kostina, Michelle Effros
This paper studies the third-order characteristic of nonsingular discrete memoryless channels and the Gaussian channel with a maximal-power constraint. The third-order term in our…
